I'm planning to do the upgrade to CUCM 7.0.2. We currently run a cluster with CUCM 6.1.2 on two MCS7825 H3 servers, pub and sub. The main feature that we are looking to use is dual forking with Remote destinations.
I'm planning to do it first on a test environment, which currently run 6.1.2 on MCS7825H1 servers; but these do not have any licenses uploaded so I can't really test much i guess. I'm just wondering whether it will be worth binding the new PAK for version 7.0.2 to the MAC address of the testing server then after the testing I need Cisco to change it to the mac address of the production server.
Can someone please provide some feedback in terms of the upgrade to version 7.0.x. from 6.1.X. If it is not too complicated i will probably do it straight on the production servers rather than in the test environment first?
Also can someone tell me whether the Cisco Unity TSP drivers will need to be upgraded so that Unity will work with 7.0.2. The Cisco Unity TSP version currently is 8.1(2)?
I have the utmost faith in Unity/Unity Connection products, but I always prefer that these type of changes are not done remotely (call me paranoid :) That being said, I don't know of anyone who has had any issues with this TSP install.
My best advice here, would be to open a TAC Case and let them have a look at your planned procedures. I always do this for any major changes (again, call me paranoid). This way if anything does go south you have an engineer already assigned and familiar with your deployment.
Hope this helps! And best of luck!
